___________ have the highest rates of star formation

Physics
1 answer:
tankabanditka [31]2 years ago
6 0

Explanation:

Starburst galaxies have the highest rates of star formation.

Central dominant galaxies are the ones which are largest individual galaxies in the universe.

The collective activity of many supernova events in a relatively small volume of a galaxy can create galactic wind.

The energy for all active galactic nuclei is thought to come from in-fall of matter into supermassive black holes.

Radio galaxies are often characterized by sources of immense energy located hundreds of thousands of light-years away on either side of their centers.

Two objects 5 kg and 7 kg are attached to the end of inextensible string which passes over frictionless pulley
Bumek [7]

Answer:

ans:

tenson(T) = 20 N

acceleration (a) = 2.86 m/s

Explanation:

T + mg = Mg

T = Mg - mg

T = g( M - m )

T = 10× ( 7-5 )

T = 20 N

again;

T = 20

Ma = 20

a = 20 / 7

= 2.86 m/s

If object A has more mass than object B, what will object A need to accelerate at the same rate as object B?
Leni [432]

Answer:

More force

Explanation:

Object A has more mass than object B

  For object A to accelerate at the same rate as object B, it will need more force.

According to Newton's second law of motion "the net force on a body is the product of its mass and acceleration".

  Net force  = mass x acceleration

Now, if a body has more mass and needs to accelerate at the same rate as another one with a lower mass, the force on it must be increased.

Explain the relationship between speed, velocity and acceleration
Montano1993 [528]
Speed is the rate at which something covers a distance; velocity is the same but it takes into account whether it goes forwards or backwards; and acceleration is the rate of an increase in speed.
